Check whether the proximity sensors operate as desired.
Correct the position of the cams if necessary (
è
5.4 Electrical installation).
Note
The lubrication intervals depend on the product load.
Shorten the lubrication intervals to half the length in case of:
– Speed

1 m/s
– Load factor

80 %
– Ambient temperature close to +40 °C
– Frequent acceleration and braking
– Dusty and dirty environment.
To optimise the service life of the toothed belt with swivel angles less than 360°:
1. Perform the following steps after every 2 million load changes:
– Dismantle the payload and rotate by 90°.
– Mount the payload again.
– Also move the trip cams by 90° in the same direction (
è
Fig. 9 in chapter 5.4 Electrical installation).
A different part of the toothed belt then comes into the load zone of the gears.
2. Repeat commissioning.
